Seismic data regularization for marine wide azimuth data

Imaging subsalt structures under the complex overburdens is a challenging task in seismic exploration due to the poor illumination of seismic waves. To solve the illumination problem, geophysicists designed the wide azimuth acquisition. Moreover, WAZ acquisition improves the signal to noise ratio by increasing the azimuthal fold, and reduces multiple interferences in the final images (Etgen, 20...

Explicit Seismic Data Depth Extrapolation by anImproved

| A two{dimensional circularly symmetric lter, which is stable, not{aliased, compact and also suuciently accurate was designed to perform explicit downward extrap-olation of the seismic waveeeld by means of the one{way acoustic wave equation. In a rst step the design of a 1D lter was performed in the wavenumber domain by using Tchebychee approximation, while the lter was applied in the space do...
